“The philosopher Hegel argued that music is so necessary because it rehearses in the language of the body concepts and truths we are in danger of losing touch with when they reach us only through our rational faculties. Music is, he said, “the sensuous presentation of the crucial ideas”. We may – for example – know in theory that keeping going is important, but it can take a song like Don’t Give Up (from Gabriel’s So) to turn a cliche into an effective call for redemption.”
